Over 10 g of non-stoichiometric Cu(2) ZnSnSe(4) colloidal nanocrystals for thermoelectric applications are prepared after one single reaction. The obtained pellet made from the colloidal nanocrystals shows a peak ZT value of 0.44 at 450 °C, which is similar to those of state-of-the-art Cu(2) ZnSnSe(4) -based bulk materials at the same temperature.
经单次反应可制备超过 10 g 的非化学计量比 Cu(2) ZnSnSe(4) 胶体纳米晶，用于热电应用。由胶体纳米晶制成的压坯在 450°C 时表现出 0.44 的峰值 ZT 值，与同一温度下的先进 Cu(2) ZnSnSe(4) 基块状材料相当。
